Question

At a certain temperature and pressure, 1 L of CO2 gas weighs 2.05 g.

What is the mass of 1 L of NH3 gas at the same temperature and pressure?​

Answer 1

Answer: .793g

Step-by-step explanation:

.205(1mol/44.01) x=(1/17.031)
.205(1/44.01)(17.031)=x
.793g=x

I had this as a problem on my hw and it was confirmed right

Answer 2

1.35 g (1mol CO2 / 44.01 g CO2) /1 L = x (1mol N2 / 28.02 g N2) / 1 L

x = 0.86 g N2
